HENRY POCOCK, OF LONDON, ONTARIO, CANADA.

BUILDING-BLOCK MACHINE.

To all whom it may concern:

Be it known that I, HENRY Pocooin, a subject of the King of Great Britain, and a resident of the city of London, in the county of hfiddlesex, in the Province of ()ntario, Canada, have invented a new and useful Building-Block lviachine, of which the following is a specification.

This invention relates to a machine for making blocks of cement or concrete.

The object of the invention is to provide mechanism for rolling the cement or concrete block from its molded to its discharging position in such a manner that the V ireshly molded cement block is carried by the machine instead of by the arms of the operator, which makes this part of the operation connected with the manufacture of building blocks in this machine light and easy for the operator, and the operation of rolling being the application of all parts of a curved surface to a plane, the block is smoothly, easily, quickly and gradually delivered to its discharging position, and being thus delivered there is no likelihood of the freshly molded block being jarred to cause it to break or collapse, practically therefore, every block made on this machine is perfect.

A further object of the invention is to so construct and arrange this machine that the face of the block will be in the bottom of the mold, and thus make it a face down machine or one in which the blocks may be faced in the most eiiicient and rapid manner with a richer material than the body of the block, if required.

A further object of the invention is to adapt the core to be placed at any position in the block, and in such a manner that any size of core can be used in any size of block, and thus meet every architectural require ment such as a small core opening where great crushing strength is required.

A. further object is to adapt a core to be withdrawn vertically thus permitting the use of wetter material, if required, in manufacturing building blocks, and the removal. of the core vertically from the freshly molded block, after the block is rolled from its molded to its discharging position, avoids and completely prevents any possibility of said freshly molded block from collapsing, which it would be very likely to do if the core was withdrawn horizontally from a freshly molded block before the latter was Specification of Letters Patent.

moved from its molded to its discharging position.

A further object of the invention is to make blocks for all widths of walls with the one mold by adjusting the same according to the width of wall required.

A further object of the invention is to make blocks for all widths of walls on the one width of pallet, one set of pallets therefore only being required to make all widths of blocks with this machine, instead of a set of pallets for each width of block.

A further object is to adapt the mold to make blocks of any length, form or design and at the same time provide a machine that will be simple, strong and durable in construction, inexpensive to manufacture, and

efficient in practical use. And this invention consists of the improved construction and novel combination of parts of thesame as will be hereinafter first fully set forth and described and then pointed out in the claims. Reference is had to the accompanying drawings forming part of this specification wherein Figure 1 is a side view of a machine embodying my invention.

29 indicate extension plates, one of which is rigidly secured to each end. of the back plate 18 by the bolts 30 for the purpose of lengthening said back plate 18 and consequently the length of the mold at the back, and said extension plates 29 are each provided with perforated lugs, 1, similar to and for a similar purpose as the perforated lugs 19 secured to said back plate 18.

31 indicate extension plates which are secured to the outer face of, and near each of the side edges, of the rolling frame (5 by the bolts 32, for the purpose of increasing the width of the rolling frame at a point opposite the back plate 18, and the rolling frame 6 serving as the front plate of the mold, the width of the front plate of the mold is consequently increased. And said extension plates 31 are each provided with a locking flange, .9, in a similar position and for a similar purpose as the locking flange 28 on the rolling frame 6, and, "u, a recess formed in each of said extension plates 31 to receive the locking flange 28 over which they are placed.-

33 indicates the vertically removable core, and 34 the cement or concrete block formed by this machine.

35 indicates a supplemental frame which is interposed between the plates 16 and the face plate 14:, to raise said face plate 14 in the mold for the purpose of making a thin or veneer block on this machine.

In a machine constructed as described, the blocks are rolled from their molded to their discharging position, the advantages of which are hereinbefore set forth, and the curved segments 7 being provided with the flanges, a, are retained on the tracks 3 without any effort on the part of the operator. And in this machine the bottom plate 1 1 of the mold forms the face of the block, and said bottom or face plate 1 1 is secured to and supported by the bracket 18, and said bracket 13 is secured to the rolling frame 6, by the bolts, 2', engaging with one of the series of bolt holes 12 formed in opposite sides of said rolling frame (3, so that by removing the bolts, 2', the bracket 13 as well as the face plate 14 secured thereto, may be adjusted upward or downward on said rolling frame 6, and held at the position to which it is adjusted by engaging the bolts,z', with one of the series of screw threaded bolt holes 12 in the opposite sides of said rolling frame 6. And this being a face down inachine, or one in which the bottom plate of the mold forms the face of the block, the width of said block will be the distance from said face plate 1 1 to the top of the back plate 18, so that by adjusting the bracket 13,

on which said face plate 11 is mounted, upward or downward, cement or concrete blocks of varying width may be formed in the one mold, and a further variation in the width of the cement or concrete blocks may be formed by inserting the supplemental frame between the bracket 13 and the face plate 1 1, when so arranged the distance from the face plate 1 to the top of the back plate 18 will be considerably reduced, after which by adjusting said bracket 13 on said rolling frame 6 thin veneer blocks of varying thickness may be fornji d, thus adapting the one mold to make blocks for all widths of walls by adjusting the same according to the width of all required. Again by securing extension plates and 31 to the back plate 18 and rolling frame 6, respectively, blocks of varying lengths as well as blocks of varying widths may be formed on the one mold. And the face plate 1 1 being removably secured to the b racket 13 by the bolts and plates 16, one face or bottom plate 1a: may be readily and easily removed, and another face plate with any pattern or design formed thereon may be secured to said bracket 13, thus readily and easily adapting this mold to make blocks with any required design or pattern on their face. A d further, in a maehine constructed as described, the pallet 17 is held between the rolling frame 6 and a portion of the bracket 13, and its lower edge is supported on the shoulder 11, consequently this pallet 17 extends from the top of the rolling frame 6 to a point below the face plate 141, as shown in Fig. 2, one set of pallets therefore will only be required to make all widths of blocks with this machine, a greatsaving is thus effected over machines in which a set of pallets is required for each width of block.

In operating this machine the rolling frame 6 is adjusted to the position shown in Fig. 2 the swinging end doors 21 to the position shown in Fig. 4t, and the whole are rigidly and firmly held together by engaging the locking levers 26 with the locking flanges 28. The mold thus formed is partly filled with cement composition and tamped down, and the core 33 inserted or lowered vertically and placed horizontally therein to the position shown in Fig. 2, this insures the perfect tamping of the portion of the cement block below the core, the mold is then filled with cement composition tamped down, struck off, the locking levers 26 are disengaged from the locking flanges 28, and the rolling frame carrying the block is rolled from the position shown in Fig. 2 to the position shown in Fig. 1, the core 33 is then removed vertically from the block and the pallet and block placed to one side out of the way to dry.

When operated as described the core 33 is inserted vertically and placed horizontally in the mold and raised vertically out of the block after the freshly molded cement block 34 has been rolled from its molded to its dis charging position, and this removal of the core 33 vertically after said freshly molded cement block 3% has been rolled from its molded to its discharging posit-ion, permits the use of wetter material, if required, in manufacturing building blocks, and also completely prevents any possibility of said freshly molded block from collapsing which as before stated it would be very likely to do if the core was withdrawn horizontally from a freshly molded cement block before the latter was removed from its molded to its discharging position. And as herein set forth, the core 33 is inserted vertically and placed horizontally in the mold, and being so placed in position, any size of core may be used in any size of block, and thus readily and easily meet every architectural requirement such as a small core opening where great crushing strength is required, as well as other prac tical advantages which are hereinbefore set forth, and at the same time provided a face down block machine that will be simple, strong and durable in construction, inexpensive to manufacture and efficient in practical use for simplicity in adjustability, wide range of blocks, ease of operation and large capacity per day.
